摘要
寡糖是动植物生长发育过程中一类重要的信号，可以调节多种反应。寡糖可以影响豌豆茎切段的伸长及烟草外植体的形态发生，还可诱导乙烯产生和果实成熟。在植物抗病防卫反应中，寡糖可以诱导植保素的合成及蛋白酶抑制剂的合成，并可诱导对病毒的抗性。植物和真菌细胞壁降解时产生的寡糖片断均可作为信号诱导植物的抗病防卫反应。庚－β－葡聚糖和寡聚几丁质的结合蛋白已经得到鉴定。寡糖信号转导过程中有磷酸化和去磷酸化的发生，膜的过氧化，并涉及到离子流和活性氧的产生等。
Oligosacchrides were important signals that can regulate many responses during animal and plant growth and development Oligosacchrides could affect elongation of pea-stem segments and morphogenesis of tobacco explants They could also induce synthesis and accumulation of phytoalexin, proteinase inhibitors,and resistance to virus Binding protein of hepta--glucan and oligochitin have been identified Transduction of oligosacchrides signals involves phosphorylation and dephosphoralationm, ion flux, member peroxidation, production of active oxygen species
